VRELE(9)		 BSD Kernel Developer's Manual		      VRELE(9)

NAME
     vrele — Release a previously obtained primary reference for a vnode

SYNOPSIS
     #include <sys/param.h>
     #include <sys/vnode.h>

     void
     vrele(struct vnode *vp);

DESCRIPTION
     The caller is holding a primary reference to the vnode and wishes to
     release it.

     vp	 The vnode being released.

     Any code in the system which obtains a primary reference to a vnode via
     vref(9) typically releases that reference with vrele() when it is fin‐
     ished with the vnode.  Upon release of the last primary reference, the
     vnode will be deactivated and either moved to the free list for later re‐
     use or marked as being cache.  The vnode can be reactivated at any time
     prior to the system reusing it.
